yTo @ZZ 'Lf/71,0777, 7175 T11/rtf] concern:

Be it known that I, FRANK ERNEST NELSON, a citizen of the United States, residing at Santa Barbara, in the county of Santa Barbara and State of California, have inver'ited new and useful Improvements in LiquideFuel-Burn* ing Apparatus of which the following is a specification` Y j My invention pertains to liquid fuel burn ing apparatus such as designed more particularly for use in the fire boxes of cooking stoves and domestic work in general; and it consists in the peculiar and advantageous apparatus hereinafter described and particularly pointed out in the claim appended.

In the accompanying drawings, forming part of this specification: Figure 1 is an end elevation on a smallscale of-the'fapp'aratus constituting the present and preferred embodiment of my invention. Fig. 2 is an en larged, longitudinal centralsection .of the inf,

jector burner or sprayer of the apparatus.

Fig. 3 is an enlarged detail section illustrative of the manner in which the core of the in]ec-' tor burner bears at its inner end against the casing of the burner. Fig. 4 is a longitudinal, vertical section, on an enlarged scale, of the steam generating retort of the apparatus.

Fig. 5 is a cross-section taken through the catch and hold anysalts, alkali or sediment that may be present in the water which is supplied to the generator through the pipe C which is equipped with a valve 'D and has its upper end disposed so as to discharge water directly into the receptacle B, as best shown in Fig. 5. It will be apparent thatsubsequent to the removal of the closure cap F at the outer end of the retort, the receptacle B may be readily withdrawn from the retort and as readily discharged of the sediment which it has collected. For the purpose of normally holding the cap F tight against the outer end of the retort A, I prefer to employ g the construction shown which is similar to that disclosed in my Letters-Patent No.

795,409 of July 25, 1905, and comprises a yoke G having intur'ned ends a removably engaged with diametrically opposite lugs on the retort A, and also having a central aperture c through which loosely extends a threaded stem d iixed to the cap F, and a nut H mounted on the said stem d and disposed at the inner side of the outer portion of the yoke. This construction is advantageous since when the nut II is turned .in one direction the cap F will be moved away from the outer end of the retort, and the cap and its appurtenances may then be removed from the retort. It will also be noted that through the medium of the said construction the cap may be expeditiously fastened in a steam tight manner against the outer end of the retort.

. The injector burner or sprayer of my appa- .ratus comprises acasing e which is designed td extend through a wall in the fire box of a stove, and a core cr plug f removably arranged in the casing e for a purpose presently pointed out. The casing e is provided with an inlet port g, connected by a valved pipe 7i with the retort A, and a liquid-fuel inlet port c' connected with a valved pipe leading from a source of hydro-carbon supply (not shown) and it is also provided in its forward en d with a central aperture 7e, and in rear of its forward end with alst-@n chamber Z, while in rear of the said steam chamber it is interiorly threaded to its rear end, as indicated by m.

The forward end wall of the steam chamber Z v in casing e is beveled or slightly inclined out- `wardly, as indicated by n, for an important vpurpose which will be presently pointed out in detail. rIhe core -o'r plug f of the injectorl burner or sprayer I is exteriorly threaded at p to engage the interior thread m of the casing e, and is' provided with an oii chamber r and a circumferential groove s which latter communicates with the oil inlet port i and is connected by ports t with the oil chamber r, as best shown in Fig. 2. Said core or plug f is also provided with a reduced forward end u designed to snugly occupy the aperture 7c in the forward end of the casing e, and a flange U located immediately in rear of the said reduced end u and having a circular corner w designed to bear against the beveled or outwardly declined forward end wall n of the steam chamber l. By virtue of this construction, it will be apparent that when the VCore or plug f 1s turned homefin the caslng e,

the circular corner w of the former will bear against the wall n of the latter with the result that the joint between the forward ends of the said core or plug and casing will be ren` dered perfectly ously an important advantage. The core or plug f is further provided in its forward end with an oil discharge aperture and rearwardly diverged passages y which extend between and connect the said aperture x with the steam chamber Z. By virtue of this latter provision it will be apparent that when steam is supplied to the chamber Zit will pass therefrom through the passages y and hence will create a s u 3 ti o n at the aperture :r with the result that the oil willbe'torn into atoms by thejetmsrrofsteam"at/such/point, and the two will be discharged into the iire box in the form of a highly inflammable vapor which will burn without the production of smole or soot.

The casing e of the injector burner or sprayer K I is preferably of octagonal form in cross section exteriorly, and the head z-of the core or plug f, which head is designed to rest outside of the lire box, is preferably of the same form in crossesection, Fig. 1, and is' prefererably7 though not necessarily, provided with a diametrical aperture a. From this latter it follows that by applying a wrench to the head z or passing a lever rod through the aperture a the core or plugf may be expeditiously and easily turned out of the casing e, and may then be readily and thoroughly cleared of collected sediment. It will also be apparent that the core or plug f may be as easily turned into the casing to carry the circular corner w thereof against the outwardly inclined forward end wall n of the steam chamber Z in the casing e for the purpose before pointed out in detail.

In the practical operation of my novel apparatus, water is supplied to the receptacle B in the retort A, and the said retort A is initially heated by any suitable means until steam is generated therein. The valve of the pipe 7L being open supplies steam to the injector burner I, and the valve in the pipes y' and C are opened to assure the proper supply of oil and water when the inflammable I vapor being ignited at the discharge end of steam tight, which is obvithe injector burner I the operation will be continuous g the heat afforded by the combustion of the vapor then serving to generate steam in the retort A.

It will be gathered from the foregoing that my novel apparatus is adapted to light or heavy oils, is well adapted to withstand the usage to which such apparatus is ordinarily subjected, and is susceptible of being readily and thoroughly cleared of collected sediment when necessity demands.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

An injector burner comprising a casing having a steam chamber in its forward portion and anfopening in its forward end and salo having the forward end wall of the steam chamber inclined outward and rearward from said opening, and a core or plug removably arranged in the casing and containing an oil chamber adapted to be connected with a source of oil supply and having a reduced forward end portion occupying the opening' in the forward end of the casing and a flange located in rear of said reduced end portion and provided with a sharp corner bearing against the inclined forward end wall of the steam chamber in the casing and also having a central discharge aperture communicating with and extending forward from the oil chamber and two or more passages extending rearward and outward from said central aperture and connecting the same with the steam chamber.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- IlGSSQS.
